. WATCH-PENDAN '1.

Specification of Letters Patent.

Application filed. August 3, 1920. Serial No. 401,044..

To aZZ whom it may comer-n Be it known that I, Louis E. F. VvAGI-ITER, acitizen of the United States, residing at New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Watch- Pendants, of which the following is aspecification.

My invention relates to certain new and useful improvements in watchpendants, and the principal object of my invention is to produce aconstruction in which deep openings in the pendant may be used for theends of the bow, and also to enable a bow of such strength to be used toprevent the ends of the bow coming out of the recesses either by thebending of the bow or the springing of the sides, and also to providemeans. whereby when desired the bow may be readily disconnected from thependant and removed without the necessity of bond ing or springing thebow.

With these and other objects in view my invention consists in certainconstructions, combinations and arrangements of parts several forms ofwhich will be first described in connection with the accompanyingdrawing and then the invention particularly pointed out in the appendedclaim.

Referring to the drawing wherein I show several forms of this inventionand wherein the same part is designated by thesame ref erence numeralwherever it occurs,

Figure 1 is a central longitudinal section through a pendant employingmy invention with parts shown in elevation;

Fig. 2 is a central longitudinalsection through a slightly modified formof constructlon from that shown in Fig. 1;

Fig. 3 is a central longitudinal section through a pendant showing astill further modification in which the bow is provided with ball ends;

Fig. 4 is a sectional longitudinal section through a pendant coveringanother modification in which the bow is also provided with ball ends,and

Fig. 5 is a plan view of one member forming the pendant.

In Fig. 1 the pendant comprises a body portion 10 centrally bored toreceive the stem of the watch. Formed on this body portion is a collar11 of any desired shape, said collar being located intermediate the endsof the body portion. Above the collar the body portion is shown asslightly enlarged at 12, and then at its upper end provided with areduced screw-threaded portion 14. Mounted on the body portion andresting with its lower surface on the upper surface of the collar 11 isa ring 15 shown in detail in Fig. 5, this ring being provided atdiametrically opposite sides with the semicircular depressions 16. 17 isa second ring similar-in construction and shape to the ring. 15. Therings 15 and 17 are together of such a thickness as to equal the heightof the enlarged portion 12 of the pendant and are mounted thereon.

18 is a nut threaded to engage the threadedportion 14 of the pendant andhold the rings 15 and 17 securely in position. In assembling the partsthe ring 15 is first placed over the portion 12 with its lower surfaceresting against the collar 11. The ends 19 of the how 20 are then placedwithin the depressions 16 while the rings 15 and 17 are separated andthen the two rings brought together. Then by screwing the nut 18 on tothe threadedportion ,17 and turning it down tight the parts will besecurely held in position. It will thus be seen that the grooves 16 maybe made of ample depth to give the ends of the bow ample bearingsurface, and thatthe body of the bow can be ofample thickness to preventany springing of the bow which would permit of the ends 19 coming out ofthe bearings 16 in the rings 15. i

In the modification shown in Fig.2 the body portion of the pendant isformed with a flange 21 in which are formed the bearing grooves for theends 19 of the'bow 20.

22 is a ring provided with grooves to form the other halfv of thebearings for the ends 19. This ring is held in position bya nut 1 23 asdescribed in connection with the form shown in Fig. 1. It will be seenthat the only diiference between the forms shown in Patented July 5,1921.

In Fig. 3 the pendant comprises the body portion 10 having the collar 11formed integral with the body portion. Resting upon the top surface ofthis collar is a'ring 2 1 having depressions 25"formed on diametricallyopposite edges to form bearings for the ends of the how 26, the ends ofthe bow in this case being shown as formed into balls 27 and thebearings in the collar 24 being of a shape to partially surround theballs.

28 is a second collar similar in shape to the collar 24: and havingcorresponding depres sions 25 in opposite sides of its circumference, sothat the two depressions will'together form complete bearings for theballs 27 of the bow 26.

The pendant is provided, as in Figs. 1 and 2, with a nut 29 to hold therings 24 and 28 together, and thus lock the balls 27 on the ends of thebow in their bearing sockets.

In Fig. 4 I have shown a construction very similar to Fig. 8, in whichthe pendant coinprises the body portion 10 and has a collar 11 thereon,on theupper surface of which is mounted the ring 24: having thedepressions 25 in opposite sides thereof for the balls 27 on the ends ofthe bow 26.

I also provide a second ring 28 having depressions corresponding to thedepressions 25 in the ring 21, the two rings being held together by thenut 29 screwed on the threaded upper end of the body portion 10 of thependant.

It will be understood that the balls may be omitted from the ends of thebows in the constructions shown in Figs. 3 and 4-, and also that suchballs may be used if desired in connection with the constructions shownin Figs. 1 and 2.

It is to be noted however that in all the constructions shown thebearings for the ends of the bow are made in two halves into which theends of the bow may be inserted without springing the bow or changingthe shape of the bow after the ends are in place, and then the twohalves secured into position to form bearings for the ends of the bow.Also that a crown may be applied to the pendant with a portionoverlapping the outer surface of the nut or ring 18, 23, or 29, whichring will then act as a guide to the crown in its revolutions.

Considerable variation of the details as described herein may beresorted to without departure from the spirit of the invention which isto be construed in the light of the following claim.

Having thus described my invention what I claim as new and desire tosecure by Let ters Patent is:

A watch pendant, comprising, in combination, a body portion having aplane upper surface and comprising semi-spherical bear ing projectionsextending diametrically from the main portion thereof, said projectionseach having a substantially semi-spherical depression in its planesurface, a cylindrical portion extending above said plane surface, aremovable body portion having a plane surface adapted to fit on saidfirst named surface, and bearing projections and depressions to registerwith the first named bearing projections and depressions, said removableportion fitting over said cylindrical portion and a cylindricalretaining ring secured to the projecting end of said cylindrical portionto hold the pendant in assembly, and providing an outwardly cylindricalsurface standing above the assembled pendant.

In testimony whereof I aflix my signature in the presence of twowitnesses.
